Don't ask me why, though. Perhaps Eric will chime in.
Define "works for me". $ ./exectest.sh First exec: Done. exec 0<&5 echo "Second exec: Done." exit 0 Here, the cat uses fd 0 (which is still set to the pipe from the here-doc), and consumes it by echoing the remainder of the here-doc to stdout, so that when /bin/bash goes to read the next line, fd 0 is at EOF, and you never execute the "exec 0<&5" line in the shell. Thus, the process never tries to duplicate fd 5 back to fd 0, and your example no longer hangs waiting for input from the terminal. But it doesn't do what was originally intended (that is, allow /bin/bash to execute the remainder of the here-doc). -- Eric Blake -- Unsubscribe info: http://cygwin.com/ml/#unsubscribe-simple Problem reports: http://cygwin.com/problems.html Documentation: http://cygwin.com/docs.html FAQ: http://cygwin.com/faq/
